Strap Mount question
The sizes of chimney strap mounts all seem to be 12' or 18', pretty long,
can these be cut down to fit a smaller chimney, like this? http://forum.tvfool.com/attachment.p...9&d=1466259687 |
I have always been wary of mounting to a chimney,but that's just me.
They can be shortened w/ the clips where the straps fold over inside and are crimped. Be sure to make your measurements w/ the bolts loosened as much as possible while still protruding all the way through the nuts. Try to get the 3 corners bent in the correct spot and level on the first try before tightening. Be sure not to over tighten to the point where the brackets start to bow. |

They should be like a banding strap. Push through the clip, fold back over itself and secure w/ the two tabs.
I have not heard of many people having a problem w/ chimney mount, but once was enough for me. |
Biggest problem with a chimney mount is the chimney.
An old one with weak and deteriorated mortar can get blown over in a storm from the wind load on a big antenna setup. As long as the chimney is in good shape should be fine. |
Another thing that just hit me, are the two lengths of pipe that you mentioned.
I would not use any lengths of pipe above the rotor, greater than needed for clearance. |

Keep the length of the stub mast above the rotor as short as you can, the bearings in the drive unit will live a lot longer. Elevate the whole drive unit instead.

Just did a chimney mount on a 2 story house, my 32' ladder was barely tall enough.
Next one I do I'm going to rent one of those bucket lifts on a trailer. It's $150 for half day, but beats falling off the roof! |
